set up check

hi guys n gals, have a new set up its a cupboard grow in 3ft x 2 ft 5 ft high so 6 square ft. using a 250w mh, humidifier set at 60% day 40% night as they are seedlings at the mo, temp set at 26c day and 21c night, fan taking in fresh air as well 2 bubble buckets big bang and kush ph at 5.2- 5.4 no nutes at the minute as i only planted them 2day. should this work or is there any thing ive missed? would appreciate any input just to make sure its right.
many thanks .

Welcome to the forums. Sounds good but a pic would help. BTW good luck with the Big Bang, as I am also growing this strain.

ok if your doing hydro, you pH is off by .5 thats a decent amount. if your doing soil, your pH is WAY OFF. 5.8 in hydro, 6.8 in soil.

also, HPS in a small space is tough because of heat problems, and when the plant grows, you could see the tops burning, and raising the light will be an issue.

tryed to grow big bang auto fem, but only realized how much light was needed for the grow tent which was 4ft x 4ft x 7ft and i was using the same 250w mh, didnt know it was the size of space not the amount of plants so they grew extremely slow and bud production was nxt to none. so moved set up in2 smaller closet for a second try. hope it works out this time. for newbies its just trial and error, but this seems to explain the poor growth. thanks man will try to get some pics up as soon as i see the rate of growth, when should i add nutes as there in bubblers there isnt any nutes.

bubblers mate, ghs say 5.5 for big bang is optimal. heat isnt a problem as its only about 8c where i am ive had to get a heater to raise it.
